Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

As shown in fig. 1 to 7, the multifunctional wrench provided by the present embodiment includes a wrench head 1, a handle 2 and a screwdriver 3, the wrench head 1 is provided with a bayonet 11 and a clamping rod 12, the bayonet 11 is used for clamping, sleeving a nut or a bolt fastener, so as to detach and install such fastener, at this time, the utility model discloses the function of wrench is played.

Be equipped with first card hole 21, second card hole 22 and third card hole 23 on the handle 2, screwdriver 3 includes interconnect's handle of a knife 31 and tool bit 32, first card hole 21 and second card hole 22 are located respectively the both ends of handle 2 and the hole depth direction of first card hole 21 and second card hole 22 are unanimous with the length direction of handle 2, third card hole 23 is located between first card hole 21 and the second card hole 22 and the hole depth direction of third card hole 23 is perpendicular with the plane that wrench head 1 was located mutually, kelly 12 detachably imbeds first card hole 21, at least two handle of a knife 31 detachably imbeds respectively interchangeably second card hole 22, third card hole 23 is used for using the lever push rod. The lever pusher can be replaced with an unused screwdriver 3.

When the first card hole 21 of kelly 12 embedding, screwdriver 3 embedding second card hole 22, this moment the utility model discloses can play the screwdriver function, the operator can hold between the fingers wrench 1 by hand and rotate, dismantles the installation to screw type fastener with screwdriver 3, the utility model discloses a screwdriver 3's function.

As shown in fig. 5 or fig. 6, when the clamping rod 12 is inserted into the first clamping hole 21, and two screwdrivers 3 are inserted into the second clamping hole 22 and the third clamping hole 23, respectively, the screwdrivers 3 inserted into the third clamping hole 23 can be right the utility model discloses a screwdriver function plays the helping hand effect, can be right again the utility model discloses a wrench function plays the effect of being convenient for to operate, explains as follows:

when the screwdriver functions, the bit 32 of the screwdriver 3 inserted into the second clamping hole 22 is clamped into a screw type fastener, then a lever push rod is inserted into the third clamping hole, the lever push rod can be replaced by the rest unused screwdrivers 3, and then the screwdriver 3 inserted into the third clamping hole 22 is pushed to rotate the handle 2, so that the mounting and dismounting of the screw are realized, and compared with the above-mentioned mode that only the wrench head 1 is rotated by hand, the pushing mode has the advantages that: a force point can be added to play a role in assisting, and even a hammer or the like can be used for knocking the screwdriver 3 inserted into the third clamping hole 22, so that the locked screw can be conveniently detached.

When playing the spanner function, bayonet 11 presss from both sides tightly, entangles nut, bolt class fastener, then inserts a lever push rod at the third bayonet hole, and this lever push rod can utilize remaining screwdriver 3 not used to replace, then promotes the screwdriver 3 of inserting third bayonet hole 22 in order to drive the handle 2 rotatory, realizes dismantling the installation of nut, bolt class fastener, and this kind of promotion mode lies in for directly promoting the rotatory advantage of handle 2: this way the operation of the wrench function can be performed very easily when the handle 2 is so close to certain obstacles that the operator's hand cannot grip the handle 2.

In the present embodiment, the screwdriver 3 has a plurality of screwdriver bits, and each of the screwdriver bits 32 has a straight shape, a hexagonal prism shape, a cross shape, a star shape, and a quincunx shape. The third engaging holes 23 are provided in plurality at intervals in the axial direction of the handle 2. The tool bits 32 with various shapes can be used for disassembling different types of screws, and the third clamping holes 23 are provided with a plurality of screw drivers 3 which can be inserted into the third clamping holes simultaneously, so that the force-bearing area of the hand of an operator is large when the operator holds the hand, and the operation is comfortable.

Third card hole 23 is the through-hole, the one end that is close to tool bit 32 on handle of a knife 31 is equipped with projection 33, works as screwdriver 3 detachably part stretches into when third card hole 23, projection 33 supports handle 2 sets up the aim at of projection 33: when the screwdriver is used, the handle 2 is propped against the convex column 33, and the screwdriver 3 cannot move to one side, so that the operation is convenient; when the wrench is used, the convex column 33 is also propped against the handle 2, the screwdriver 3 can not fall down, and the operation is convenient. Of course, the above-mentioned effect can be achieved if the third card hole 23 is a blind hole.

The cross sections of the first clamping hole 21, the second clamping hole 22 and the third clamping hole 23 are hexagonal, and the clamping rod 12 and the tool shank 31 are hexagonal prisms, so that a specific mode that the wrench head 1, the handle 2 and the screwdriver 3 cannot rotate mutually is provided, and other modes capable of achieving the purpose can be adopted.

The quantity of bayonet 11 has a plurality ofly and every bayonet 11 has different sizes, can satisfy and dismantle different kinds of nut, bolt class fastener.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
